The previous question was:Give the MW of nitrogen gas to 4 significant figures. From the periodic table, N = 14.01What are the units ?MW = __1__A. grams        B. amu        C. mol        D. FU        E. atoms        F. no units _______

What type of reaction is this ? C7H14 + O2 → CO2 + H2O

Calculate the %O in Fe2(SO4)3 to 4 significant figures.%O =__1__%

Balance the reaction.note: Add four numbers.__1__ Cu  +  __2__ IrF3  →  __3__ CuF2   +  __4__ Ir _______ _______ _______ _______

note: For this exam we won’t select a letter to designate a number, instead we can just input the number. Don’t add extra symbols such as a decimal point at the end of a number. The answers are numerical such as 3, or 1.06, or 50.0%. Use 3 significant figures for ΔEN and % ionic character. For the Lewis electron dot formula for the compound between magnesium and nitrogen, magnesium nitride, there are __1__ magnesium ions, and __2__ nitride ions. The magnesium ion has __3__dots while the nitride ion has __4__dots. The ΔEN = __5__, the % ionic character is __6__%.note: the electronegativity values are Mg = 1.31, and N = 3.04 ΔEN is on top, %ionic character is on bottom.  ΔEN of 1.6 corresponds to 47% ionic character. 1.0  1.1  1.2  1.3  1.4  1.5  1.6  1.7  1.8  1.9  2.0  2.1  2.2  2.3  2.4  2.5  2.6  2.7  2.8  2.9 22    26   30   34   39   43   47   51   55  59   63  67   70   74   76   79   82.  84   86   88  note: the next question asks for the type of bonds

How many oxygen atoms in 10.0 g of Fe2(SO4)3 ?note: 1 mol = 6.022 x 1023 thingsnote: don’t use scientific notation for the first answer, use 3 significant figures for both answers(10.0 g) =__1__mol Onote: use scientific notation as follows, 6.022 x 1023 = 6.022E23(10.0 g) =__2__atoms of O

The textbook is required for this course.

Credit will be assigned for attendance.

You gave the patient  20 cc of contrast rather than 10 cc, how should you proceed?

Give examples of information that you may chart as a technologist.
